7 Rahat has a recipe for muffins that uses 2 cups of four for 18 muffins
He wants to halve the recipe.
How much tour wil he need?

the answer is 1

Step-by-step explanation:

if you are splitting the recipe in half then just split the amount of the ingredients in half too

half of the 2 cups of flour would be 1 cup of flour

you would also get 9 muffins instead of 18 muffins

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
